5.Erica David lives in Pinedale,Wyoming,USA,where winter can bring temperatures of below 35degrees Fahrenheit,howling winds,and a lot of snow.So it was just natural that she chose to study snow for her school science fair in the sixth grade.
Now a junior in high school,Erica is in her sixth year of snow experiments,and is well on her way to becoming a snow expert.She started with a basic question:Could snow fences be built to work better?
Snow fences are used to keep snowdrifts(雪堆)from covering areas like roads of train tracks,or to help build up snow where it can help with water shortages in spring when it melts(融化)."Also,I wanted to protect my animals better from blowing snow,"says Erica,who raises goats,sheep,and pigs.
Before she could test fence designs,Erica had to figure out what would act like real snow in her experiments."I tested flour,sugar,and salt before I settled on dishwasher powder,"she explains.
Science fairs offer students the chance to test theories,present findings to judges,and meet other researchers.Erica's many achievements include competing at the Discovery Channel Young Scientist Challenge for middle school students and the Intel International Science and Engineering Fair,where students from around the world present their science research.
But perhaps the best reward is that her research is already being put to good use.She has come up with an improved snow fence design,and this year she's helping think out how to provide water supply to native plants,which have been killed off by drilling at nearby natural gasfields.
"Science fairs are an amazing experience,"says Erica."Just pick your true feeling and go for it."

72.What does the passage suggest to us?C
A.Science fairs are held for high school students in America.
B.Erica is the youngest show expert well known in America.
C.The environment brought much convenience for Erica to study snow.
D.The hope to contribute to her hometown made Erica experiment on snow.
73.In Erica's hometown,snow fences may play a part inD.
a.reducing the harm blowing snow does to animals
b.supplying water resource to the nearby gas fields
c.making up for the lack of water resource.
d.keeping the traffic smooth
A.a,b,c            B.a,b,d             
C.b,c,d            D.a,c,d
74.Science fairs are attractive to students because theyB.
A.can have their research put into practical use
B.can have their scientific ideas tested out
C.are allowed to help protect the local wildlife
D.can learn about the most advanced technology
75.Which of the following material can best replace snowing in Erica's experiment?D
A.Flour.         B.Sugar.
C.Salt.          D.Dishwasher powder.

20.It was December 25,1914,only 5months into World War I.German,British,and French soldiers,already sick and tired of the senseless killing,disobeyed their superiors and started socializing with"the enemy"along two-thirds of the Western Front.
German troops held up Christmas trees with signs"Merry Christmas".Thousands of troops ran across the battlefields covered with dead bodies.They sang Christmas songs,exchanged photographs of loved ones back home,shared food and even played football.Soldiers hugged men they had been trying to kill a few short hours before.They agreed to warn each other if their officers forced them to fire their weapons,and to aim high.
Fear ran through the military leaders on both sides.They felt that their power was being challenged:soldiers declaring their brotherhood with each other and refusing to fight.Generals declared this unexpected peacemaking illegal and said that participating soldiers would face a military court.Those found guilty would be imprisoned or even shot.By March 1915the socializing movement had been destroyed and the killing machine was back in full operation.Over the next three years more than fifteen million people died in the war.
Not many people have heard the story of the Christmas Truce (休战).On Christmas Day,1988,a local radio host in Boston played"Christmas in the Trenches",a song about the Christmas Truce,several times and was   stunned by his listeners'response.Thousands of people called in,praising the song,with many moved to tears by the amazing events it described.
You can probably guess why the callers were in tears.The Christmas Truce story goes against most of what we have been taught about people.It lets us see the world as it can be and says,"This really happened once."It shows us the potential we have as humans,and contradicts all of those TV and newspaper stories that tell us how mean and heartless people are.It is like hearing that our deepest wishes really are true:the world really can be different.

24.The soldiers began socializing with the enemy becauseA.
A.they couldn't bear the meaningless killing
B.it was the best way to avoid being killed
C.they feared that they would be caught
D.their enemies were from similar backgrounds
25.How did the generals finally put an end to the soldiers'socializing?D
A.They sent the soldiers'loved ones to prison.
B.They moved the two groups of soldiers further apart.
C.They increased the number of officers to control the soldiers.
D.They warned the soldiers that they would face severe punishment.
26.The underlined word"stunned"in Paragraph 4most probably meansB.
A.satisfied         B.shocked
C.amused            D.confused
27.The author uses the story of the soldiers to imply that human beingsC.
A.are not trustworthy under stress
B.are naturally aggressive and war-like
C.are basically caring and kindhearted
D.will always do what is in their own self-interest.
